GRATE FOR VAPOR-STOVES.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Original application filed April 26, 1901, Serial No. 57,559. Dividedand this application filed December 5, 1901. Serial No 84,824.

To all whom it may concern.-

Be it known that I, WILLIAM H. WILDER, a citizen of the United States,residing at Gardner, Worcester county, Massachusetts, have inventedcertain new and useful Improvements in Grates for Vapor-Stoves and theLike, of which the following is a specification.

My invention relates to improvements in oil-stoves, and particularly tothe form of grating upon which the articles to be heated are supported.

The present application is a division of the application filed by meApril 26, 1901, Serial No. 57,559.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation, and Fig. 2 is a plan view.

As illustrated in the drawings, there is a base-plate A and corner-postsB, extending upward therefrom, these corner-posts being suitablyconnected by webs of sheet-iron.

The top of the stove comprises end castings D and E, and secured tothese castings are two tubes 2 2, made of sheet metal bent into tubularform and extending between the castings, and these tubes serve as asupport for the open-work sections or gratings F F. These sections areduplicates of each other, and their front and rear under faces at theiredges are partially curved to fit the rounded upper surface of thetubular supports. The gratings are made of open-work, so as to allow forthe ready passage of the heat; but just at the center is an opening, asshown at 3, while alongside of this opening is an im perforate disk ofmetal made integral with the grating, as shown at 4. The burners which Iuse in connection with this form of grate or top are movable, asdescribed in my aforesaid application, and it will thus be seen that theburner may be adjusted to bring it directly beneath the opening 3 whenit is desired to get the full effect of the heat, and when it is desiredto deflect or divide the heat the burner may be swung beneath theimperforate section A. The gratings being removable and reversible maybe arranged, as shown in Fig. 2, with the openings alongside of eachother or they may be reversed, so as to bring the imperforate sectionsalongside of each other, or these parts may be arranged alternately, asthe circumstances of the case may require. The casting D has anextension (Z of skeleton work which projects out sufficiently to protectthe reservoir located directly beneath it, as described in mypreviousapplication.

The arrangement shown and described of the cast-metal end sections andwith the intermediate side rails of sheet metal of cylindrical shapemake a very desirable construction and a very strong one, preventing thewarping of the parts, as is common where sheet metal tops are used. Anopen-top frame is thus provided with removable gratings, giving freeaccess to the burners or working parts of the stove for all purposes.The gratings are supported only by the side rails and have slidingconnection therewith, being readily removable, reversible, andinterchangeable.

I prefer to make the gratings in single sections that is, as manysections as there are burners. hen access is desired to one burner, thegrating above it may be lifted and placed upon the adjacent section, andif access is then desired to any other burner the grating above it maybe moved by sliding upon the side rails.

It will be understood that I do not limit myself to the use of thegratings with a stove having movable burners, as the form of frame andgrating will be .found of value in connection with stoves having fixedor stationary burners. The gratings can be reversed when used in such astove to change the imperforate portion, as may be found desirable inits relation to the burner.

I am aware that it has been proposed to form the top of a stove of arectangular frame with a central opening with a grating fitted to theopening and suitably supported by the rectangular frame, as in my patentdated July 22, 1890, No. 432,847. In my present invention, however, thestove is without a permanent top, having simply supports extendinglengthwise at the front and back adapted to receive and sustain asection in the form of a grating and constituting the entire top of theprising end sections, and an intermediate sec tion supported by the siderails, substantially as described.

In testimony whereof I afiix mysignature in presence of two witnesses.

WILLIAM H. VVILDER.
